Frequency Converter Variable Frequency Drive / VFD

2、 In some countries, industrial power consumption is three-phase 380v, but most small power AC motors support star angle connection conversion, which means that a three-phase 380v motor with star connection can be converted to a three-phase 220v motor with triangle connection, so that it can be safely adapted to frequency converter speed regulation. The star angle conversion method can be referred to the following figure:

3、 If the motor is not marked with a convertible connection or the three-phase 380V itself corresponds to a triangular connection, it cannot be converted. Please purchase a three-phase 380V converter or use a single-phase 220V to three-phase 380V boost converter;

4、 Please select a suitable frequency converter and corresponding control method based on the type of load. The overload capacity of the motor in a short time is generally higher than that of the frequency converter. When the load is large (reaching or exceeding the rated current of the motor), please select a frequency converter with a higher power level or two levels.

(Note: Please change the voltage level corresponding to the connection method based on the motor nameplate.)
